XR-E Thermal Temperatures, Q5 versus Q2?

[kramer5150]

Curious... does one generate more heat than the other when driven at 1-1.2A?

 

[jar3ds]

they shouldn't as long as their vf is the same...

Actually, if the vf is the same, the Q2 will generate a little more heat thanks to less energy escaping as photons.
